CentOS 6.6 源码编译安装MySQL 5.7.18教程详解

一、添加用户和组

1.添加mysql用户组

# groupadd mysql

# useradd -g mysql -s /bin/nologin mysql -M

# rpm -qa | grep mysqlmysql-libs-5.1.73-3.el6_5.x86_64# rpm -e mysql-libs-5.1.73-3.el6_5.x86_64 --nodeps

# yum -y install wget gcc-c++ ncurses-devel cmake

1.下载最新版本的MySQL

进入http://dev.mysql.com/downloads/mysql/，选择Source Code下的Generic Linux。选择带boost库的mysql下载。MySQL5.7对boost库有要求，选择带boost库的会避过一些坑。

# wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.18.tar.gz

2.解压并安装

# tar xf mysql-boost-5.7.18.tar.gz# cd mysql-5.7.18# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_USER=mysql -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=boost/boost_1_59_0# make && make install

# cd /usr/local/mysql# mkdir data

# chown -R mysql. /usr/local/mysql

# ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

1.之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃
2."--initialize"会生成一个随机密码(~/.mysql_secret)，而"--initialize-insecure"不会生成密码
3.--datadir目标目录下不能有数据文件
4.使用--initialize参数后，一定要记住生成的密码，否则无法登陆数据库。

6.拷贝启动文件到/etc/init.d/下并重命令为mysqld

# /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

安装完后发现没有my.cnf配置文件，手动创建个

# vim /etc/my.cnf[mysqld]basedir =/usr/local/mysqldatadir =/usr/local/mysql/dataport = 3306socket = /tmp/mysql.sock[client]socket=/tmp/mysql.sock

# /etc/init.d/mysqld start

# /usr/local/mysql/bin/mysql -uroot -p系统生成的密码

mysql>set password = password(‘新密码‘);mysql>flush privileges;mysql>exit

# /usr/local/mysql/bin/mysql -uroot -p‘新密码'
